[0028] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0029] The present invention provides the following preferred embodiments:

[0030] Example 1, as Figures 1-7 As shown, an eccentric rivet riveting device includes a base plate 1, a rivet seat 5, a pressing mechanism, a cleaning mechanism, and a fixing mechanism. The pressing mechanism is installed on the top of the base plate 1, the rivet seat 5 is fixed on the base plate 1, the cleaning mechanism is located on one side of the rivet seat 5, and the fixing mechanism is located above the rivet seat 5. A groove 29 is provided at the top of the rivet seat 5.

[0031] The pressing mechanism includes a rivet joint 4 and a lifting assembly. The lifting assembly is fixed to the top of the base plate 1, and the rivet joint 4 is installed below the lifting assembly. The pressing mechanism drives the rivet joint 4 to move downward, and the groove 29 above the rivet seat 5 enables the riveting of the workpiece.

[0032] The cleaning mechanism includes a flipping component, a transmission component, and a cleaning component. The flipping component is located below the rivet seat 5, the transmission component is located at one end of the flipping component, and the cleaning component is located at the end of the transmission component away from the flipping component. The flipping component dumps the debris remaining on the top of the rivet seat 5, and the transmission component can transfer the kinetic energy generated by the flipping component to the cleaning component, so that the cleaning component cleans the rivet head 4.

[0033] The fixing mechanism includes several mounting slots 8 and multiple fixing rods 9. Each mounting slot 8 is opened on the top of the riveting seat 5, and each fixing rod 9 is fixedly installed on a mounting slot 8. By setting mounting slots 8 at different positions, the fixing rods 9 can be installed in mounting slots 8 at different positions to fix workpieces of different sizes.

[0034] like Figures 1-7 As shown, the lifting assembly includes a support frame 2 and a first cylinder 3. The support frame 2 is fixedly installed above the base plate 1, the first cylinder 3 is installed on the top of the support frame 2, and the rivet joint 4 is installed at the output end of the first cylinder 3.

[0035] After the workpiece is positioned, the first cylinder 3 at the top of the drive support frame 2 pushes the rivet head 4 downward, pressing the top of the eccentric rivet and forming the rivet head by pressing the rivet head, thus connecting multiple workpieces.

[0036] like Figures 1-7As shown, the flipping assembly includes an L-shaped plate 19, a second cylinder 10, a push block 11, a connecting shaft 12, a hinge rod 13, a slide groove 14, a hinge shaft 15, a base block 16, two rotating blocks 17, and two fixed blocks 18. The L-shaped plate 19 is fixed above the base plate 1. The second cylinder 10 is fixedly mounted on the top of the L-shaped plate 19. The push block 11 is fixedly mounted on the output end of the second cylinder 10. Specifically, the push block 11 slides on the L-shaped plate 19. The connecting shaft 12 is mounted on the end of the push block 11 away from the second cylinder 10. The slide groove 14 is formed at the hinge rod 15. The connecting shaft 12 is inserted into the inside of the slide groove 14 on the surface of the rod 13. The end of the hinge rod 13 away from the connecting shaft 12 is fixedly connected to the hinge shaft 15. The bottom block 16 is fixedly installed above the bottom plate 1. Two rotating blocks 17 are fixedly installed above the bottom block 16. Two fixed blocks 18 are fixedly installed below the rivet seat 5. The two rotating blocks 17 are rotatably connected to the hinge shaft 15. The two fixed blocks 18 are fixedly connected to the hinge shaft 15. A pad 30 is provided between the bottom block 16 and the rivet seat 5. A collection box 7 is provided on one side of the bottom block 16.

[0037] After prolonged use, debris generated during rivet processing will adhere to the outer wall of the rivet joint 4 and the groove 29 above the rivet seat 5. At this time, by driving the second cylinder 10, the second cylinder 10 pushes the push block 11 to slide on the top of the L-shaped plate 19, causing the connecting shaft 12 to slide as well. Since the other end of the connecting shaft 12 is located in the slide groove 14 and the connecting shaft 12 is fixed to the surface of the push block 11, it slides parallel to the push block 11. When the connecting shaft 12 slides parallel, it can drive the hinge rod 13 to rotate along the axis of the hinge shaft 15. The rotation of the hinge rod 13 drives the hinge shaft 15... 5 is rotated, causing the two fixed blocks 18 fixed on the outer wall of the hinge shaft 15 to rotate. When the fixed blocks 18 rotate, they will drive the riveting seat 5 to rotate around the hinge shaft 15 as the center, which will quickly rotate the groove 29 on the top of the riveting seat 5, dump the debris inside the groove 29, and install a collection box 7 at the dumping position so that the debris is collected into the collection box 7 for concentration, thereby cleaning the groove 29 on the top of the riveting seat 5. When the riveting seat 5 is reset, a pad 30 is installed between the riveting seat 5 and the bottom block 16. The pad 30 can support the riveting seat 5.

[0038] like Figures 1-7As shown, the transmission assembly includes a vertical plate 6, a first gear 20, a second gear 21, a first pulley 22, a second pulley 23, a belt 24, and a rotating shaft 25. The vertical plate 6 is mounted on the top of the base plate 1. One end of the hinge shaft 15 is rotatably mounted on the vertical plate 6. The first gear 20 is fixed at the end of the hinge shaft 15 away from the hinge rod 13. The second gear 21 is rotatably mounted on one side of the vertical plate 6 and meshes with the first gear 20. The first pulley 22 is fixedly mounted on one side of the second gear 21. The rotating shaft 25 is rotatably mounted on one side of the vertical plate 6. The second pulley 23 is fixedly mounted at one end of the rotating shaft 25. The belt 24 is sleeved on the outer wall of the first pulley 22 and the second pulley 23.

[0039] When the hinge shaft 15 rotates, it drives the first gear 20 on one side to rotate. Since the first gear 20 and the second gear 21 mesh with each other, the second gear 21 is driven to rotate. Because the diameter of the first gear 20 is larger than that of the second gear 21, the second gear 21 will accelerate when it rotates. Since the second gear 21 and the first pulley 22 are coaxial, the first pulley 22 will rotate simultaneously when the second gear 21 rotates. The first pulley 22 and the second pulley 23 are connected by a belt 24. When the first pulley 22 rotates, it will drive the second pulley 23 to rotate. Since the diameter of the first pulley 22 is larger than that of the second pulley 23, the second pulley 23 will be further accelerated when it rotates. When the second pulley 23 rotates, it will drive the rotating shaft 25 fixedly connected to one side to rotate synchronously, and drive the fan 26 at the end of the rotating shaft 25 away from the second pulley 23 to rotate.

[0040] like Figures 1-7 As shown, the cleaning assembly includes a fan 26, an air blower 27, and multiple air inlets 28. The fan 26 is fixed to the end of the rotating shaft 25 away from the second pulley 23. The air blower 27 is sleeved on the outside of the fan 26. The multiple air inlets 28 are all opened on the outer wall of the air blower 27.

[0041] It should be noted that the air outlet of the conical air blower 27 is directly opposite the bottom of the rivet joint 4;

[0042] The fan 26 generates wind by rotating, and a conical air blower 27 is installed on the outer wall of the fan 26 to concentrate the wind and blow air onto the rivet joint 4. Multiple air inlet slots 28 are provided at the end of the air blower 27 away from the rivet joint 4, so that when the fan 26 rotates, the airflow can enter the air blower 27 through the multiple air inlet slots 28, thereby cleaning the rivet joint 4.

[0043] like Figures 1-7 As shown, several mounting slots 8 are formed on the top of the rivet seat 5, and each fixing rod 9 is installed on a mounting slot 8 by bolts;

[0044] Specifically, the mounting groove 8 has an internal thread, and each fixing rod 9 is fixed with a mounting plate on the side away from the workpiece. The mounting plate has holes that match the mounting groove 8. The mounting plate can be fixed to the top of the mounting groove 8 with bolts to fix the fixing rod 9.

[0045] When two or more workpieces need to be riveted, first place an eccentric rivet in the groove 29 opened inside the riveting seat 5, align the two or more workpieces with the eccentric rivet and place them on the upper surface of the riveting seat 5. Depending on the size of the workpieces, install a fixing rod 9 on the mounting groove 8 at the corresponding position on the top of the riveting seat 5. The workpieces are positioned by installing fixing rods 9 at all four corners of the riveting seat 5.

[0046] like Figures 1-7 As shown, the diameter of the first gear 20 is larger than that of the second gear 21, and the diameter of the first pulley 22 is larger than that of the second pulley 23;

[0047] By making the diameter of the first gear 20 larger than that of the second gear 21, the second gear 21 is accelerated and transmitted through the first pulley 22. By installing the second pulley 23, which has a smaller diameter than the first pulley 22, a second acceleration is achieved. Through multiple accelerations, the hinge shaft 15 can drive the fan 26 to rotate at high speed, blowing air onto the rivet joint 4 to achieve a cleaning effect.
